In order to get the original colors, all pigments were studied chemically. The color pigments were made of gold, azzurit (a rare and very expensive mineral), rare elements and lacks. A particular attention was given to the "biacca" ( a lead-white made out of lead-calcium basic carbonate (PbCO3)2 · Pb(OH)2and a precursor of our zink- and titanium white) - which during the centuries had turn from white to dark brown. Similarly, it was noticed that the azurit had become greenish. 27 "stories" in Giotto paintings were thus first digitally photographed and scaled down at 10% of the original (30cm x 30cm), digitally retouched and then manually hand painted using watercolours and gouache. Over 3 years of work.

Giotto's legend as the perfect painter is quite know. Reportedly, he could draw a perfect circle with free hand.

A courtier from Pope Benedict IX told Giotto that the Pope wanted to make use of his services and asked him for a drawing which he could send to his holiness.
At this Giotto took a sheet of paper and a brush dipped in red, closed his arm to his side, and with a twist of his hand drew such a perfect circle that it was a marvel to see. Then, with a smile, he said to the courtier: "There's your drawing."
As if he were being ridiculed, the courtier replied: "Is this the only drawing I'm to have?"
"It's more than enough," answered Giotto. "Send it along and you'll see whether it's understood or not."

From "Stories Of The Italian Artists" translated into Eglish from Vasari (1908)

Giotto was the first "star" artist in Western art.

Dante Alighieri was one of his contemporaries and he saw the paintings above on the making. He Wrote about Giotto in his "Divina Commedia" (Purgatory, Canto XI) when he states that he clearly outperformed Cimabues' fame.
